I know nothing about 3D printers and I ordered this printer because I came to know that it is a fully assembled machine. So I thought that the printer will work straight out of box and I will not have to spend a lot of time while assembling. Yes, the printer came as fully assembled machine but still I faced various problems while assembling it. I printed on PLA which was a huge disappointed as the prints were of really poor quality and not even close to being exact. Even the slid-in build plate gets jammed in between the printing process and leads to a huge mess. I am disappointed with my purchase.
